Answer:
   16.8°
Step-by-step explanation:
The Law of Cosines can be rearranged to give the angle measure.
   angle Q = arccos((p² +r² -q²)/(2pr))
   angle Q = arccos((690² +450² -290²)/(2×690×450))
   angle Q = arccos(594500/621000) ≈ 16.7985°
The measure of angle Q is about 16.8°.

Let the width be w, length = 3w and height = 2w
Volume = length x width x height = w x 3w x 2w = 6w^3
6w^3 = 2,058
w^3 = 2,058/6 = 343
w = ∛343 = 7
width = 7 cm

Answer:
-3.5 ( or -7/2)
Step-by-step explanation:
we can substitute the point into this function to find out the answer
that is:
4 = m*(-2) -3
7 = m*(-2)
m = 7 / (-2)
m = -3.5
